T 0 all whom, it may concern: w

Be it known that I, RUDoLF Gauss, manuf acturer, a citizen of Prussia, and a subject'of of Prussia, residing at Schneidemi'ihl, A to Bahnhofstrass'e 29, in the Kingdom. of Prussia and German Empire, have invented certain new and useful Improvements in Couplings for Connecting a Driving- Motor with a Driven Machine, of which the following is a full, clear, and exact description.

This invention relates to a coupling by means of which a working machine, first, which is connected with the motor by means of a belt-pulley or a tooth-wheel gear can be put in engagement, so that it is set in action I by the motor, or, second, can be-put out of engagement, so that the motor continues to rotate, the working'machine, however, gradually ceasing to act and finally becoming stationary, but which, third, can be so put chine which has been put out of engagement with the motor comes to a standstill immediately, as is necessary in the case of accidents tothe working machine.

In the accompanying drawing, a coupling of the kind is illustrated in vertical section and in the uncoupled position. I The example selected is that of. an agricultural machineviz., arotary or winding machine. In this case the shaft a, of the motor engages, by means of a tooth-wheel b, with a tootl1wheel g, which is loosely seated on the drum-shaft a between the two adjusting-collars d and f. This tooth-wheel g may be replaced by a beltulley connected I with the motor by means 0 a belt.

The tooth-wheel g carries a Conicallyturned clutch-ring h. Correspondingly to this a coupling-ring i is seated onthe drumshaft in such a manner that it participates in the movement of the shaft 0 through the medium of a key 7:, but can be moved to the right or to the left on the shaft. This movement is effected by an adjusting-lever Z, which is seated on the machine-frame n,'so that it can be swung out on the center m, and I by means of a pin 0 engages in the groove p, formed in the sliding piece g of the couplingring *5. The machine-frame, moreover, carries a fixed brake-ring 1", the brake-surface of which corresponds to the coupling-ring.

W'hen the coupling is in the position indi cated in the drawing, the motor-shaft a rotates the tooth-wheel 9 through the medium of the tooth-wheel b. As this wheel, however, is loosely seated on the shaft 0, the shaft is not influenced. Thus the Working machine is out of engagement and the motor runs idly. If, however, the lever Z is moved I to the left, as indicated by the arrow 1, the coupling-ring i is pushed over the clutch-ring h, and the clutch-surfaces s and t of the two parts come in contact with one another. The toothed wheel 9 is thus coupled with the drum-shaft .0, so that the latter participates in the rotary motion of the motor-shaft a and the machine is driven. If the lever motion just described is effectcd'slowly, theworking machine is put gradually in engagement and the motor gradually put under strain. If, however, the lever Z be moved to the ri ht in the direction of the arrow I I, the sha t c is again uncoupled. The consequence is that the motor continues to work. The drumshaft, however, rotates gradually more slowly and thus becomes stationary. If the lever Z be moved still farther to the right in the direction of the arrow I I, the external brakesurface at of the coupling-ring engages with the brake-surface v of the brake-ring 1', so that the coupling is at once firmly held, and the shaft 0 comes suddenly to a standstill.

As will be seen without further explanation, the coupling described above can be employed for all kinds'of machines in which a startin a disengaging, and a sudden stopping o the Working machine is required. The coupling of the working machine with a motor may be effected either with a hand or a foot lever.
